The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

Through a one-of-a-kind experiment at the Department of Energy's Oak Ridge National Laboratory, nuclear physicists have precisely measured the weak interaction between protons and neutrons. The result ...

Physical Review Letters, PRL, the world’s premier physics letter journal, has published two papers by a team of Louisiana State University nuclear physics researchers to advance the knowledge on the ...

Physicists have spent decades treating mass as something the universe simply hands to particles, a property encoded in ...

Physicists are exploring whether hidden dimensions and the shape of space could help explain why fundamental particles have ...

A new result from the Q-weak experiment at the Department of Energy’s Thomas Jefferson National Accelerator Facility provides a precision test of the weak force, one of four fundamental forces in ...

A spinning neutron disintegrates into a proton, electron, and antineutrino when a down quark in the neutron emits a W boson and converts into an up quark. The exchange of quanta of light (γ) among ...

A new surprising result from digging in Fermilab archives could help scientists uncover new laws of physics and solve mysteries such as the nature of dark matter. In a new study appearing in the April ...

The Large Hadron Collider (LHC) sparked worldwide excitement in March as particle physicists reported tantalizing evidence for new physics — potentially a new force of nature. Now, our new result, yet ...

Over the years, humans have come up with four forces that can be used to describe every single interaction in the physical world. They are gravity, electromagnetism, the weak nuclear force that causes ...

“You can do it quickly, you can do it cheaply, or you can do it right. We did it right.” These were some of the opening remarks from David Toback, leader of the Collider Detector at Fermilab, as he ...
